GEORGE A. WILSON, 3B,, OF BOSTGN, MASSACHUSETTS, ASSIGNOB OF ONE-HALF TO GEORGE A. WILSON, OF BOSTQN, lvEASSAGHUSETTS VALVE.

Application filed March 30, 1920. Serial N0. 369,959.

rticu- .nnlrs 10 with a float, it may be applied to any kind of valve structure, and it consists in a particular construction comprising a ball valve which is free to move in the valve chamber except as it may be held against the valve seat by suitable means when. passage of liquid throughthe valve seat is not desired. The advantage oi? a ball and esp cially a freely-movable ball is that the portion of its surface which engages the valve seat is constantly changing so that while in time it may wear the valve seat somewhat, the wear will be spherical in character though the same parts of the valve surface will not necessarily contact with the valve seat at all 5. times. Thus it will always grind its own 1 seat. I

My invention will be understood by rot erence to the drawings in which it is shown in its preferred form.

Figure 1 is a longitudinal. section showing the application of 'alve to an orcinary float such as is used in a water-closet tanl: and elsewhere.

Fig. 2 is a side view partlyin section showing the valve as applied to faucet.

Referring especially to l. 65 is acastin; having a passag therethrough connected at one end to a pipe 10 whicl water inlet, and having a valve seat A. walls of the passage beyond said val serving as a guide passage for the va ve 4 and the plunger 3. A porti-or oi? the p: sage is shown, at The casting 65 has a hollow spherical or enlarged portion 6i within which is a chamber 62 through which passes the walls of the passage. said chainher being connected. with the passage by openings 7 and 8 through its walls. 11 is the outlet from the chamber 62 which as shown is threaded on its interior in order to be connected with a suitable discharge pipe (not shown). 10 is the inlet pipe which has at its connectingend a conical enlargement 101 by means of which and a cap nut 9 it is connected to the end of: the casting 65 to form a watertightjoint.

t is the valve which is spherical and which is normally held against itsseat by a plunger 3 sliding in the enlarged portion of the passage 5, and this plunger is connected to a trigger or lever 2 by a loose pivoted joint 21 which trig er is pivoted as at 63 to a bracket 66 on the casting 65. The loose joint between parts 2 and 3 is provided so that the plunger 3 may be given a movement in line with the axis of the passage in which it runs. To the trigger 2 is attached a lever 1 at the outer end of which is the ordinary float (not shown) tiis lever being attached to the trigger by athumb screw 12. T and 8 are opening connecting the passage 5 with the chamber 62 and outlot 11. The casting 65 carries a'bracket or support 6 of ordinary construction by which may be attached to the tank.

It will be seen that in the operation of this device when the tank empties, the float drops and turns the trigger '2 around its pivot 63, thus withdrawing the plunger 3 *trom the ball l so that the hall yielding to the water pressure entering the passage 5 from pipe 10 will move away from the valve allowing the free entry of water through a assages '2" and 8 to the chamber 62 "from which it will flow out through the outlet 11.

The construction shown in Fig. 2 is to all intents the same. 10 being the inlet and 11 being the outlet. 7 and 8 being openings connecting thepassage in the inlet 10 with the chamber 62, 8 being the plunger 4; the valve and X the valve seat. In this case however, the plunger 3 is held in place by the plungrer rod 81. The means for operating the plunger rod 31 to restrain and release the valve 4 is not shown except by the handle 32 said passage, 3 ball valve adapted to fitsaicl seat, and means for holding said ball valve to its scat anrl releasing it therefrom.

2. A valve comprising a casting having a passage therethrough, said casting having a hollow spherical enlargement, tl1e Walls of said passage having openings inrougli which said passage communicates with the chamber of said enlargement, an outlet passage manwa with which said. chamber communicates, an 10 inlet valve seat located in said passage, a ball valve adapted to fit said seat, a plunger fitting said passage and engaging said ball valve, and means for operating said plunger to hold said valve to its seat or release it 15 therefrom.
